Luminous device with changeable color and brightness

1. Technical Field

The present disclosure relates to a luminous device with changeable color and brightness.

2. Description of Related Art

Color and brightness of light emitted from a conventional luminous device can be changed with a predetermined time elapse. However, the color and brightness of the light emitted from such a luminous device is often changed according to a predetermined program, and cannot be adjusted by the user.

The components of the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout several views.

FIG. 1 is a schematic view of a luminous device in accordance with an exemplary embodiment.

FIG. 2 is a schematic diagram of a cover of the luminous device of FIG. 1 .

FIG. 3 is a block diagram of the luminous device of FIG. 1 .

FIG. 4 is a flowchart of a method for controlling the luminous device 1 to emit light with different color and brightness.

FIG. 1 is a schematic view of a luminous device 1 in accordance with an exemplary embodiment. The color and brightness of the light emitted from the luminous device 1 can be changed according to external inputs. The luminous device 1 includes a light source 11 , a cover 12 , and other necessary components. In this exemplary embodiment, a desk lamp 1 is taken for example. The desk lamp 1 further includes a base 13 . The light source 11 is covered by the cover 12 . In this exemplary embodiment, the light source 11 consists of a plurality of LEDs. The cover 12 is made of light transmissible material. The cover 12 is divided into a plurality of areas according to coordinates of the cover 12 . Each area of the cover 12 is assigned a distinctive color and brightness and is operable to be touched to activate the light source 11 to emit a corresponding color and brightness.

As shown in FIG. 2 , the luminous device 1 further includes a plurality of touch sensors 14 . The touch sensors 14 are disposed in the inner surface of the cover 12 . The touch sensors 14 generate input signals in response to touch operations on the cover 12 . Each area of the cover 12 is assigned at least one of the touch sensors 14 for generating the input signal to activate the light source 11 to emit a corresponding color and brightness when being touched.

As shown in FIG. 3 , the luminous device 1 further includes a controller 15 , a data storage 16 , and a power 17 . The controller 15 controls the light resource 11 to emit light with different color and brightness. The data storage 16 stores a relationship between each of the areas and the color and brightness values emitted by the light source 11 when each of the areas is touched. The controller 15 periodically scans the touch sensors 14 to determine whether the touch sensors 14 generate the input signal and which touch sensor 14 generates the input signal. Typically, the controller 15 further determines which area the determined touch sensor 14 belongs to and thus determines the touched area on the cover 12 . After determining the touched area on the cover 12 , the controller 15 accesses the corresponding color and brightness value of the determined area from the data storage 16 , and controls the light source 11 to emit the light with the accessed color and brightness value. The power 17 provides power for the light source 11 , the controller 15 , the data storage 16 , and the touch sensors 14 .

FIG. 4 is a flowchart of a method for controlling the luminous device 1 to emit light with different color and brightness. In step S 401 , the controller 15 detects whether the touch sensors 14 generate an input signal. If the input signal is not detected by the controller, the step goes to itself.

In step S 402 , the controller 15 determines which touch sensor generated the input signal if the input signal detected by the controller.

In step S 403 , the controller 15 further determines the touch area corresponding to the determined touch sensor.

In step S 404 , the controller 15 accesses the corresponding color and brightness value of the determined area from the data storage 16 .

In step S 405 , the controller 15 controls the light source 11 to emit the light with the accessed color and brightness value.

Although, the present disclosure has been specifically described on the basis of preferred embodiments, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the disclosure.
